ABSTRACT:
A transformer structure is proposed herein which includes a primary winding coil, a secondary winding coil, a bobbin module, and a magnetic core assembly. The magnetic core assembly is mounted within the bobbin module. The bobbin module includes a first winding window portion and a second winding window portion in which the first winding window portion allows the primary winding coil to be wound thereupon and the second winding window portion allows the secondary winding coil to be wound thereupon. Both of first winding window portion and the second winding window portion include a first lateral plate, and each couples or separate with each other by the first lateral plate, such that the primary winding coil and the secondary winding coil are separated with each other and the leakage inductance, and the safe distance of electrical security for the transformer is increased accordingly.
